- Application filed January 7, 1915. Serial No. 892.

citizen of the United States, and resident of Milwaukee, in the countyof Milwaukee and State of Wisconsin, have invented certain new anduseful Improvements in Spindle- Head Brush-Holders; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof.

My invention has for its object to provide a simple, economical andeffective brush tip for bottle-washing macl1ines,its construction andarrangement being such as to dispense with screw-couplings, keys or-likede vices requiring time and delicate manipulation, such devices inpractice having been found to -frequently work loose or jam underconstant use.

Thus the generic object of my invention is to provide a couplingconnection between the removable brush-head and tip, which connectionmay be eifected by snapping the elements together and confining them bya spring-controlled dog, the dog being incased within a spindle head tothus present no obstruction with reference to the diameter of said head.

With the above and other minor objects in View the invention consists incertain peculiarities of construction and combination of parts as setforth hereinafter withreference to the accompanying drawings andsubsequently claimed.

In the drawing Figure 1 represents a sectional elevation of abrush-holder embodying the features of my invention, the section beingindicated by line 11'of Fig. 2; Fig. 2,,a longitudinal sectional vie ofthe same, as indicated by line 2-2 0 Fig. 1, with parts shown in full;Fig. 3, a detailed crosssection through the spindle-head, the sectionbeing indicated by line 3-3 of Fig. 1, and Fig. 4c, a fragmentarysectional elevation of a portion of the head showing a modified form ofcoupling connection whereby the brush i rendered capable of oscillationwith respect to the spindle-head.

Referring by characters to the drawings, 1 represents a tip orspindle-head that is internally threaded at its lower end for thereception of a water supply spindle not shown, it being understood thatthe head, in some instances, may be shouldered and exteriorly threadedfor the reception ofthe spindle, without departing from the spirit of myinvention. The spindle-head is provided with e a centrally disposedwater duct 2 that communicates with a flattened rectangular end cavity 3for the receptionof an eye t formmg the terminal of a brush-shank 5,whichbrush-shank in this exemplification of my invention is shown in theform of a wire, the strands of which are coiled about themselves toconfine the brush-bristles that are fixed thereto in any desired mannerand shape, it being understood that the brush construction forms no partof my present invention. I

v Referring particularly to Figs. 1 and 2, it is seen that the eye 4:substantially closes the end water duct 2 and to provide a bypass forthe water, a channel 2 is provided in the head adjacent said end of theduct and com-' municating with the duct and with the said cavity.

The eye 4, as shown in Figs. 1 and 2, is formed with a rectangular endthat is socketed into the cavity 3 and the cross-sectional area of thewire i of approximately the same dimensions as the width of the cavity,whereby side play of the brush is prevented within said cavity and,owing to the straight stretches of the loop eye which engage the ends ofthe walls of the cavity lateral play in this form of my invention isalso restricted. The base section 4 of the eye is seated upon. thebottom wall of the cavity 3 and said'base section is confined by itsengagement with a jaw 6 extending from the head 6 of a snapdog, the headbeing provided with a downwardly curved nose 6" which is adapted to beengaged by the bottom stretch l of the brush loop when the same isinserted within, the cavity. The snap-dog is seated in a lon gitudinalgroove 7 that extends intermediate of the ends of the spindle-headwhereby the dog is seated entirely within the line of said spindle-head,its outer edge being normally flush with the circular outer wall of thesame. Thus the snap dog forms no obstruction in connection with thespindle-head to prevent its access to bottle necks or other articles inwhich the apparatus may be inserted. The dog also substantially closesthe groove 7 to provide the retention of water in the duct 2. By thisformation of the spin- (lle head, its manufacture by casting is greatlyfacilitated as the groove 7 and duct As shown in Fig. 1, the biting faceof the jaw 6 is slightly inclined, whereby it will exert a downwarddrawing pressure upon the stretch t of the loop at all times to thussecure the brush firmly in its coupled connection with the spindle-head.The snapdog, as shown, is pivotally mounted within its receiving groove7 by means of a pin 8, which extends through an aperture formed in thespindle-head. The snap-dogis also provided with a tail-piece 9 whichforms a continuation of the body of the dog and between the end of whichtailand its head the fulcrum is positioned. The tail-piece isprovidedwith a web-lug9 that extends into a transverse aperture 10, intowhich aperture is fitted a coiled spring 11,,being under compressionbetween the base of said. aperture and the web-lug 9 of the grippingdog. Thus it will be seen that the gripping dog is held under springtension at all times. In order to manipulate the gripping dog when it isdesired to remove the brush for renewal or other purposes, the circularouter wall of the spindle-head is formed with a crosschannel 12constituting a thumb-seat, whereby a portion of the gripping-dog tail isexposed. Thus by this means access is had to the tail of the grippingdog by the operator to force the lower portion of said dog inward inopposition to its pressure, whereby the head will recede from its normalseated position across'the rectangular cavity 3 to free the eyed shankof the brush from the spindle head.

From the foregoing description it is obvious that a brush having aneyedshank can readily be slipped into the mouth of the cavity 3 and as it ispressed downward to its seat, the curved nose of the gripping doghead'will recede and when the stretch 4 of the eye has seated againstthe bottom of the cavity the dog will, through its spring pressure,automatically snap back to effect the desired coupling.

In some instances it is desirable to permit oscillation of the brush inone direction and, in order to effect this result, I may, withoutdeparting from the spirit of my invention,

- contract the loop 4, as shown in Fig. 4 of the drawings, in suchmanner that the side stretches 4 are brought together so as to permitplay of the brush shank with relation to the end walls of its seatingcavity 3. It is also apparent that, owing to the rectangular seat 3being of such width as to only accommodate the width or dimensions ofthe loop wires, there is no appreciable liability of the brush to haveside play, whereby it might otherwise inadvertently become uncoupled.

I claim:

The combination with a brush having a shank provided with an opening ofa spindle head provided in one side with a longitudinal slot extendinginwardly of the axis of the head and forming at its inner. portion awater duct, the head being provided in oneend with a socketcommunicating with and extending transversely of the slot for receivingthe shank, the head being formed with a channel communicating with thesocket and slot and a dog pivoted longitudinally in the outer portion ofthe slot and engageable in the opening of the shank to hold said shankin the head, said dog also serving to siibstantially close the outerportion of the s 0t.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee in the county of Milwaukee and State of Wisconsin in thepresence of two witnesses.
